I think the issue is that you have switched from norm to height units without realising.
The screen is 2 norm units high but only 1 height unit.
The screen is 2 norm units wide but could be between 1.333 and 1.778 height units wide. Yours is the latter.
For text components I often go back to norm units. Height units are better for stimuli since they are the same size vertically and horizontally.
You can set the wrap width of a text component on the advanced tab. I often use 1.5 norm units.
